Good question. I don't know other than I just watched a red squirrel the other day climb up to a branch about 25ft up and hang a dried mushroom. I find quite a few drying or dried mushrooms here and there in bushes and branches. I imagine they are hiding things all summer but I don't really know for sure. Another red squirrel was harvesting the white cedar seed bundles for a few weeks until they were all gone. Eating some for sure but hauling lots away too.
I had quite a few black walnuts sprouting in my driveway this summer. I didn't want them so I was going to pull them up but by the time I got around to it the squirrels already dug them up, chewed off the spout and ate the rest!
The only time I've found a cache was the year my muffler was filled with acorns. That was chipmunks though.
